[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model discloses a portable intelligent construction power supply box for construction sites, comprising a main body 1 and a square frame 2. The square frame 2 is installed at the lower end of the main body 1. A drive rod 10 is provided on the square frame 2. A pressure plate 11 is installed at one end of the drive rod 10. A force-receiving groove 16 is provided at the lower end of both ends of the pressure plate 11. A large limit block 8 is provided at the end of the force-receiving groove 16 away from the drive rod 10. A large spring 5 is provided on the side of the large limit block 8 near the pressure plate 11. The large spring 5 is sleeved on the large limit block 8. The upper surface of the large limit block 8 is in contact with a fixing rod 9. A rotating shaft 15 is provided at both ends of the fixing rod 9. A rotating shaft 15 is provided on the rotating shaft 15. The wheel 6 and the fixing rod 9 are provided with a long inclined plate 13, a small limiting block 19, a small spring 14, a limit release lever 20, a guide groove 12, a sliding rod 4, a short inclined plate 17, a short rotating rod 18, a horizontal plate 3, a long rotating rod 7, and a long rotating rod 7 at one end of the horizontal plate 3 and a long inclined plate 13.

[0024] Please see Figure 2 The long rotating rod 7 is rotatably connected to the horizontal plate 3 and the long inclined plate 13, and the two ends of the long rotating rod 7 are set on the square frame 2.

[0025] Please see Figure 4 The drive rod 10 is welded to the pressure plate 11. The pressure plate 11 is in contact with the large spring 5. The large spring 5 is sleeved on the large limit block 8. The large spring 5 and the large limit block 8 are both in the force groove 16. One end of the force groove 16 is threaded to the square frame 2.

[0026] Please see Figure 3 The two ends of the fixed rod 9 are fixedly connected to the rotating shaft 15, and the rotating shaft 15 is rotatably connected to the wheel 6.

[0027] Please see Figure 3 The limit release lever 20 is set on the small limit block 19, the small limit block 19 is sleeved with the small spring 14, and the small limit block 19 is fixedly connected to the long inclined plate 13.

[0028] Please see Figure 3 One end of the short rotating rod 18 is rotatably connected to the horizontal plate 3, and the other end of the short rotating rod 18 is rotatably connected to the short inclined plate 17. The short inclined plate 17 is rotatably connected to the sliding rod 4, and the sliding rod 4 is rollingly connected to the guide groove 12.

[0029] Please see Figure 1 The frame 2 is fixedly connected to the main body 1, and the frame 2 is inserted into the drive rod 10.

[0030] The implementation principle is as follows: This utility model releases the wheel 6 by setting a drive rod 10. The rotation of the long rotating rod 7 drives the long inclined plate 13 to move downward. During the downward movement of the long inclined plate 13, the sliding rod 4 in its guide groove 12 moves accordingly. When the sliding rod 4 moves to the bottom of the guide groove 12, it will slide and contact the small limit block 19. The small limit block 19 is subjected to pressure and moves upward, which will cause the small spring 14 to contract. The sliding rod 4 reaches one end of the guide groove 12. At this time, the pressure of the small limit block 19 disappears, and the small spring 14 drives the small limit block 19 to return to its original state and lock the sliding rod 4, thus achieving the fixing effect. The wheel 6 has been opened and fixed.

[0031] This utility model uses a limit release lever 20 to store the wheel 6. By gently pushing the limit release lever 20 upward, the sliding rod 4 is released from its fixation. The construction power box is then slowly placed on the ground. The wheel 6 is subjected to upward pressure, which drives the fixing rod 9 upward. The sliding rod 4 moves towards the upper end of the guide groove 12 until the bottom of the power box is completely in contact with the ground. The fixing rod 9 touches the large limit block 8, which causes the large spring 5 to contract. The fixing rod 9 passes over the large limit block 8, and the large limit block 8 and the large spring 5 return to their original state, locking the fixing rod 9 and completing the storage of the wheel 6.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
